Z-lambda: A terminal-based software for simulation of heat transfer during Z-scan experiments in transparent solids

Abstract

Heat transfer is an important process in many engineering applications, including materials science and photonics. We present a Z-lambda software tool for the simulation of heat transfer in transparent solids during laser irradiation, using the heat equation and an explicit difference method. The software allows for the simulation of laser heating scenarios, including the modeling of pulsed laser heat sources. The software is able to calculate heat transfer in any isotropic transparent solid materials. It can be used to simulate the heat transfer caused by laser radiation during Z-scan experiments, by calculating the temperature distribution of the sample. The software is written entirely in C++, and it is designed to be run in a terminal. It can utilize up to 64 processor threads to perform calculations, making it a powerful tool for the simulation of complex heat transfer scenarios. Overall, this software provides a valuable tool for the modeling and simulation of heat transfer in transparent solids, and it can be used in various engineering applications. The software is available for download and use under an open-source license.
